Application filed September 30, 1926. Serial No. 138,699.

This invention relates to adelivery apparatus. V

The object of the invention is the production of an apparatuswherewithbags or other objects can be easily clamped anddelivered to apredetermined place. o The secondobj'ect ofthe invention is theproduction of an apparatus wherewith bags that are delivered from a bagmaking machine are clamped one after the other and automaticallydelivered to a predetermined place. The third object is to produce adelivery apparatus wherewith bags and other objects of differentthickness are automatically clamped and conveyed to a predeterminedplace.

In the accompanying drawings Fig. 1 represents a side elevation of thedelivery apparatus; and Fig. 2 shows a topeplan View ofFigl. f H

The apparatus in this instance comprises the pair of triangle shapedframes designated in their entireties by the numerals and 21. Each framecomprises the vertical T shaped member 24, the inclined T shaped member25, the nose end 26 and the intermediate horizontal member 27 The framesare connected by the spacer bolts 28.

To the outerfaces of the intermediate horizontal members 27 are fastenedthe journal brackets 29, which have journaled therein the driving'shaft30. 'Pulleysfil, 82- and the sprocket chain wheel 33 are fastened. tothe shaft 80. A journal bracket 38 is fastened to one side of the frame20. An idler sprocket chain wheel 40 1s journaled to the journal bracket38. A sprocket chain 44 extends over thesprocket chain wheel-33, isguided by the idler sprocket chain wheel 40, and leads to a source ofpower not shown. A shaft 48 has its ends journaled in the frames 20 and21, and has fastened thereto the pair of clamping pulleys 50 and 51 and,the pulley 52. A belt 53 connects the pulleys 31 and the pulley 52. Apair of arms 55 have their lower ends pivoted to the inner faces of theframes 20 and 21, and have fastened thereto the shaft 56, on whichlatter'are journaled the pair of adjustable clamping pulleys 58. Springs59 extend from the upper end of each arm 55, and have their other endsfastened to the frame of the apparatus.-

A journal bracket 62 is fastened to each of the vertical members 25 ofthe frames, and a shaft'65 is journaled in said brackets 1 A-shaft G6has itsendsijournaled in the nose ends :26 ofthe framesrof the.apparatus. A roller 67 is fastened to the shaft66.-=A

shaft 68'lias 'itsends journaled inthe mem-- .bers 27of the frames-20and 21,-and has fa's:

tened thereto the-roller 69. A.belt173 connects the. pulleys 32 and.69.' ;In this'instance five pulleys 7 5 .are fastened :toqthe shaft 65.

; A pair of "our nal bracketsf 78arefasteiiedto the upperportions of thevertical members 24 0f the frames 20 and 21, and have jourshaft 79. Aroller- 80 and naled thereinthe a pair of guide pulleys .81arefastenedto the A lurality of delivery belts each indicated shaft 79."A pair of journal ,arms 83 extend 1 from the verticalmembers 24 and havejournaled therein the shaft 84, to which latter is fastened the guideroller 85. A plurality of pulleys 86 are fastened to the shaft 48.Clamping-bands indicated with" the upper members 88 and the lowermembers 89 extend around the roller 80, the pulleys 86 and'bear upagainst the guide roller 85.

To use the delivery apparatus the driving shaft 30 is turned by means ofthe sprocket chain44 and its appurtenances. This causes the deliverybelts having the members76 and 76, and also the clamping bands havingthe members 88 and 89 to move. The bags or other objects to be deliveredare guided, by means not shown, and drop between the cirf cumferentialsurfaces of the pairs of clamppulleys 50, 51 and 58 are preferablyrubber covered and the flexibility of the springs 58 enable the bags andother objects of different thickness to be clamped between the said pulleys.

Various modificationsmay be made inthe invention and the presentexemplification is to be taken as illustrative and not limitativethereof.

Having described my invention what I de sire to secure by Letters Patentand claim is: 1. In a delivery apparatus the combination of a deliverybelt, a moving elampin band making an angle with the delivery belt toform a nozzle shaped space, a pair of'clamping pulleys one bearing onthe other adjacent to said belt and band, means to rotate one of saidpulleys and pliable means to hold the second pulley against therotating'pulley.

2. In a delivery apparatus the. combination of a pair of frames, arotativedriving shaft journaled in the frames, a'seeond shaft journaledin the frames on one side of the driving shaft, a pulley fastened to thesecond shaft, a roller journaled in the frames, means to rotatethe'pulley during the rotations of the driving shaft, a delivery beltsupported by said pulley and roller, a third'shaft journaledin-theframes, means to rotate the third shaft With the rotations of thedriving shaft,

a'pulley fastened to the third shaft, a second roller journale'd in theframes, a clamping band carried by the latter pulley and roller, thesaid clamping band forming a nozzle shaped spacewith the delivery belt,a clamping pulley fastened to the third shaft, a seo- 0nd clampingpulley and resilient means for holding the second clamping pulley in contact with first'clamping pulley.

3. In a delivery apparatus the combination of apair of frames, a drivingshaft ournaled in the frames, a second shaft ejournaled in the frames onone side of the driving shaft, a plurality of pulleys fastened to thesecond shaft,a roller journaled in the frameon the side opposite to thesecond shaft, a plurality of delivery belts carried by said pulleys andshaped space with one member of each delivery belt, a pair of clampingpulleys fastened to the third shaft, a pair of the frames, a shaftfastened to said arms,;a pair ofclamping pulleys journaled to the lattershaft adapted'to bear against the first pair'of clamping pulleys and aspring with one end of each fastened to one'of said arms and their otherends fastenedto said frames.

In testimony whereof I affix my signature.
